In the embodiment of the invention shown, the frame `A is composed ofelongated hcllow castings mounted one upon another. The main part of theframe comprises the base casting A and the surmounting casting A2.

The cover A3 is used to enclose the chamber which holds the roll oftape, and may be omitted, if desired. rlhe casting A comprises aperimetral wall which provides sidey walls and end walls. The casting isopen at the top and at the bottom. It is equipped with lugs 1 forconnection with the casting A2.

The casting A2 comprises side walls 2, a rear end wall 2a, and a topwall 2b which connects the upper edges of the side walls in front of thecover A". The top wall 2b terminates at its rear end in a downwardly andrearwardly extending web 2c (Fig. 4) which extends between the sidewalls 2.

The cover A3 is connected at its rear end by a pivot 3 with the rearupper portion of the cast-ing A2. The cover is in the form of a hollowcasting which presents side walls 4- and a curved top wall d which alsoforms the front and rear walls of the cover. The lower edges of the sidewalls 4 of the cover rest upon the upper edges of the side walls 2 ofthe casing A2. The front wall of the cover is cut away to provide aspace 5 which forms with the wall 2b a throat through which the paperstrip D extends. The junetion between the top wall 2b of the front endof the casting A2 and the web 2C is suitably rounded to permit the paperstrip to slide freely. As shown in Fig. 6, the top wall 2b is providedwith a longitudinal slot 21 into or through which the upper portion ofthe feed-wheel B3 extends. lt will be understood that the upper surfaceof the wall 2b serves as a bed, or guide-plate, over which the paperstrip D slides while being served from the machine.

The main actuating shaft B is journalled in bearings G 17) with whichthe casting A is provided. The actuating handle B bears normally againstan adjustable stop 7 mounted on a sector 8 which is attached to one sidewall of the casting A2 by means of screws 9. The ratchet-wheel B2 isequipped with a hub which is secured by means of a pin 10 to the shaftB. A spacingsleeve 11 is interposed between said hub and the adjacentbearing 6. About the sleeve 11 is wound a spring 12 which has one end 12engaging the pin 10. The other end 12b of the spring is connected withthe shaft F of the latching device F. as shown in Fig. 6.

rlhe feed-wheel B3 is of large diameter and extends through the slot 2dof the top wall 2l. As shown in Fig. 17, the feedwheel is provided witha hub, and the rear end of the lever E3 of the cutter-mechanism isjoined on the shaft B adjacent said hub. The spring-fastening device B4is rigidly secured to the shaft, and a washer 13 is interposed betweenit and the pivoted portion of the member E3.

This spring-fastening comprises a sheetmetal loop 1st which is bent intoU-shape, thus providing the sides 14a and the web 14th. The shaft Bextends through the side meinbers 141, and is secured with respect tothe loop by means of a small bolt 15 which is interposed between the web14 and the shaft, the shaft being provided with a transverse groovewhich receives a portion of the bolt 15. vWashers 16 are applied to theend portion of the bolt 15, these washers having tabs 16a which extendinto the space between the side members 14a. One of these washers (Fig.18) is equipped with lugs 16 which afford a socket receiving one end ofthe pack of leaf-springs B5. 'lhe bolt 15 extends through the springs,and thea springs are clamped in position, as will be understood fromFig. 11. 1t will be observed that it is impossible for thespring-shackle B4 to shift in any direction with relation to the shaftB; also, it will be understood from Fig. 17 that after the parts havebeen assembled, it is impossible for the shaft B to shift longitudinallvwith relation to its bearings.

The handle B in the form shown comprises a sheet-metal arm 17 having itsattaching end slotted to form a loop and having the loop-portion foldedinto U-form and thus providing the spaced portions 17*L and 17b and theweb-portion 17 C. The folded slotted portion receives the projectingshaft B and is keyed thereto by a transverse bolt 18 which extendsthrough the loop-end and a complemental transverse groove with which theshaft B is provided at the point 18a. The handle is equipped at its freeend with a knob 19.

The spring-pressed idle feed-roll C is jourA nailed on a horizontal pin2O (Figs. 3 and 6), carried by a sheet-metal. member 21 which isprovided at its lateral edges near its rear end with upturned lugs 21pivotally mounted on a shaft 22 whose ends are held by bearing lugs 22awith which the frame member A2 is equipped. The rear portion of themember 21 underlies the shaft 22, and the rear eX- tremity of the member21 is curved upwardly, as indicated at 2lb. The form is such as toprovide the member 2l with a rounded angle ,21C between which and therounded junction of the top wall 2b and web 2C is left a space, or slot,through which the paper strip B can pass freely.

The lugs 21a are engaged in front of the shaft 22 by the web-portion ofa spring 23 which has coils 232L encircling the shaft 22, theend-portions of the spring being e.\:- ltended downwardly through slots2st with which the wall 2b is provided. The spring 23 tends to hold thepresser-roll C against the feed-roll B3. The front extremity of themember 21 is curved upwardly and affords a tab 21( which may be engagedby the linger when it is desired to lift the presser-roll C away fromthe feed-roll. The bearing-lugs 21l are equipped with dependingprojections 21d which are adapted to engage the front walls of theslot-s 24, thus limiting the rearward swing of the member 21 andpreventing the spring 23 from being injured.

As appears from Figs. 3, l and 10, the gumnied tape roll D is receivedin a chainber D2 aiiorded by the rear portions of the casing members Aand A2 and the cover A2. This chamber is provided with a bottom D3 whichpreferably is formedof sheet-metal and which is provided at points withlugs which are clamped between the members A and A2. The member D3 is inthe form of a segment and is equipped with lateral flanges 26 which arespaced apart a suflicient distance to accommodate the largest size rollwhich can be used in the machine. When a wide roll of tape is used, itis simply dropped into the chamber D2 and is supported and held inupright position by the bottom D2. In the illustration given, a roll ofnarrow tape is shown. This roll is mounted on a core 27 carried by ashaft 28 which is equipped with threaded extremities upon which aremounted nuts 29 between which are disposed a pair of spring plates 30which can be adjusted to cause the desired amount of friction upon thesides of the core 27, or upo-n the roll, or upon both. The plates 30 areof elongated form and fit freely within the chamber D2, but do notrotate when thel tape is withdrawn. rIhe extremities of the shaft 23 arereceived in internal slots, or bearings, 3l with which the side walls ofthe intermediate casting A2 are provided.

In the illustration given, the tape D is assumed to be provided on itslower or outer side with an adhesive coating, and thus the strip passesfrom the lower edge of the roll, as illustrated in Fig. 4, so that thelower side of the strip will be brought properly into engagement withthe moistening elementwhich will be described later. Some manufacturersroll the tape with the adhesive side in. Where such a roll is employedin the machine, the roll is reversed and the tape is fed from the upperedge of the roll. In the example given, the roll is provided at one sidewith a pasteboard disk 32.

The cutting mechanism E will be understood by reference to Figs. 1-3, 5,9 and l1. The front portion of the top wall 2b of the casing 2 is cutaway, as indicated at 33, thus leaving a shoulder, as indicated at 332.J ust in front of this shoulder there is mounted upon the upper edges ofthe side walls 2 of the casing A2 a plate 34 which is provided with aslot 342 which extends across the frame, as shown in Fig. 5. Upon theplate 34 is adjusta'biy mounted a horizontal blade 35 which, as shown inFig. 52, is provided with slotted openings 352. The horizontallydisposed blade 35 and the underlying slotted plate 34 are secured to theframe member' A2 by means of cap screws 36, it being understood that theblade 35 can be adjusted for wardly or rearwardly. The front edge of theblade projects over a portion of the slot 342, as appears from Fig. 5.

The blade-carrying lever E has one end mounted on a pivot 37 carried bylugs l34b with which the plate 34 is equipped atone end. The lever isprovided at its other end with a segmental guide arm 38 which engages aguide slot 34c with which the correspondlng extremity of the plate 34 isprovided. The lever E is equipped at an intermediate point with avertically disposed cutting, or punching, blade 39 which has beveled andtapered lower edge portions which meet at a downwardly directed apex392. The purpose is to have the apex portion of the blade pierce thestrip of paper at its center initially and then punch, or shear, thepaper gradually as the lever descends. The bla-de 39 is adapted to workthrough the slot 342 and to engage more or less closely the front edgeof the horizontal blade 35. In adjusting the blade 35, the lever E maybefirst depressed and the front edge of the blade 35 may then be setagainst the rear surface of the blade 39, as will be understood fromFig. 11.

The bladeecarrying lever E is normally held in elevated position bymeans of a small coil-spring` 40 whose lower end sets in a socket 40nwith which the frame member A2 is provided, as shown in Fig. 9. Theupper end of the spring 40 bears against the lower edge of the member Ea short distance from the fulcrum 37.

The blade-carrying lever E is adapted to be depressed through the mediumof the link E2 which works through a slot 4l with which the frame memberA is provided at the upper edge of one of the side walls. It will beobserved that the frame member A2 is somewhat narrower at this pointthan is the frame member A', so that the upper portion of the link E2 isoutside of the side wall 2. The lower end of the link E2 is turnedinwardly as indicated at 42 and engages a perforation with which thefront end of the lever E2 is provided. As has been stated, the rear endof the lever E3 is pivoted on the actuating shaft B, as shown in Fig.17. At an intermediate portion, the lever is bent to extendtransversely, thus providing the transverse portion 43, which is adaptedto be engaged by the leafspring B5. which is rigidly attached to theshaft B. The lever E3 normally is held in elevated position by the latchmember F2 during the serving of the strip from the machine, the springB5 being placed under heavy flexure when the main actuating lever B isswung forwardly in the direction indicated by the arrow in Fig. 1. Atthe end of the feeding of the strip from the machine, the hand-lever Bstrikes the trip-arm F* and releases the latch member F2 from engagementwith the portion 43 of the lever E3, thus permitting the spring B5 toquickly depress the lever E2. This carries the blade 39, by a sort ofpunching action. through the slot 34 and thus causes the strip to bepunched and sheared. It will be observed in Fig. l1 that the level ofthe upper surface of the 4blade 35 is slightly below the plane of thetop surface of the wall 2b. Also, that the plane of the upper surface ofthe blade is slightly above the plane of the upper surface of the plate34. rlhis feature prevents the end of the strip from engaging the rearedge of the blade and also from engaging the edge presented by the frontwall of the slot 34 as the strip is fed through the machine. 1n theshearing operation, there is a tendency to produce a very slightdownturned fin at the front edge of the paper strip, and were it not forthe fact that the surface in front of the blade 39 is depressed,difficulty might be experienced from the paper engaging the front wallof the slot 34a.

As will bestbe understood from Figs. 3

and 6. a loose presser-plate 44 located in front of the presser-roll Cin position to hold the front end portion of the paper strip in closecontact with the upper surface of the top wall 2b. The plate 44 isequipped with a rigidly fastened lnob 44a by means of which the platemay be inserted or removed. rlhe front end portion of the plate projectsover a portion of the blade 35, and the fro-nt corners are cut away, asindicated atl 44h, to accommodate the cap-screws 3G. At its rear end,the plate44 is slotted centrally, as indicated at 44, to accommodate thepresser-rolls C. This provides rear vardly extending furcations 44hwhich project past the presser roll. The rear ger-tion of the plate iscurved upwardly, so that the paper strip E will enter readily beneath t1e iresse '-piate. lVhen desired, the presser-plate may be lifted freelyfrom the bed of the machine to expose the paper strip. In threading thestrip through the machine, the plate 44 is removed and the presser-rollC is lifted. The rock-shaft F of the latch mechanism F is journalled inthe lower porti n of the basescasting rr, the trip-arm FAl beingdisposed outside of the casting and in the path of the hand-lever l. isshown in Fig. 12, the trip-arm F is provided with a slottec loop45through which the shaft F extends, and the arm is rigidly secured inposition by means of a bolt 45t. Suitable washers 451 are provided forthe bolt, as shown in Fie'. 11. rlhe spring n E is secured to therock-shaft by means of the bolt The upper end of the spring F3 bears therear end of a sheet-metal platform 4G which, shown in Fig. 6, is securedat its outer end to lugs 47 with which the frame member fr is equippedinteriorly at its front end. The upper portion of the ront wall of themember A is cut away, as indi-cated at 48, and it will be rememberedthat the surmounting frame member A2 is not provided with front wall.Thus, the frame is left open at' its front end to enable the water-fontG to irserted by horizontal ino-vement.

The water-font and attendant parts will be best understood by referenceto Figs. 2, 6, 14 and 15. rlhe font preferably is in the form of arectangular box drawn from sheet brass and having the intermediateportion of its front wall bowed outwardly to provide an integral spout49, flanked by wall sections 49a.

rlhe holder-element of the unit- G is adapted to engage the wallsections 49 when the unit is depressed into the font. rlhe holder G2 ispreferably so constructed as to enable it to hold a thin block of feltwhich preferably is of square contour, so that any edge of the feltblock may be presented upwardly to the adhesive side of the gummed tape.The holder comprises a rectangular vertical frame member 50 whichpreferably is formed by bending a piece of sheet-metal to provide afront wall 50, edge walls 59h, and inturned rear fianges 5G. 'lfhecapillary moistenerelement G3 may be forced into the open-ended member50, which really allor-os a peripheral wall, which does not, however,extend wholly across the rear surface of the blocl-I G3. Attached to theedge walls 50 are the arms 51 of sheet-metal braclfet member which has atransverse web-portion 51n disposed back of the plane of the felt block.At the ends of the web-portion are provided upturned ears 51h which areprovided with relatively large perforations 5L". rhese perforationsreceive loosely the end portions of a small shaft, or wire, whoseintermediate portion secured to eyes punched from the sheetmetal meinbe54 which comprises a part of the presser-member rl'he member 54 isprovided at its front edge with a roll, or hollerY bead, 54a in which issecured a metal rod 54b which serves as a weight. The rear end margin ofthe member e4 is curved upwardly, as indicated at 54.

The arms 51 project in front of the wall 50a and are provided with slots51d, thus affording hooks 51e adapted to engage the wallsections whenthe unit G is inserted in the water-font. rlhe arms 51 are so spaced asto lie closely adjacent the inner surfaces of the lateral walls of thefont, so that the unit G is amply secured in position by simply forcingit down into ene lent with the walls at the rear portion of trie ront.lt will be noted from Fig. 6 that there is provided a passage 55 betweenthe web 51 and the plesser-member G4; also, it will be noted that theweighted front end of the presser-mein iter is adapted to rest upon theupper edge of the felt block G3.

The felt block may be adjusted vertically with reference to its holder,and it may be securely held in adjusted position by means of pins 56, ifdesired. These pins are adapted to extend through holes 57 with whichthe web 50a of the member 50 is provided.

After the unit, shown in Fie: 15, has been mounted on the font, shown inFig. 14, these parts may be introduced, as a unit, into the chamber 58,of which the member 46 forms the bottom. The member 46 is equipped atits rear end with a stop 46a and at its front end with a stop 4Gb.

. The position of the parts is such that when the font is in position,the rear edge of the web 512, which web is slightly inclined, isdisposed adjacent the front edge of the plate 34. The web 5la is thinnerthan the plate 34, so that the paper strip will slide freely ofi' theplate 34 and onto the web. The inclined web 51u tends to deflect theadvance end of the strip upwardly somewhat. The strip then passesbeneath the weighted portion of the plate 54 andis thereby held incontact with the upper edge of the Vcapillary moistener-meniber G3. jFig. 6 represents the condition after the knife has been operated andthe severed strip has been withdrawn. In the next forward swing of thehand -lever B, the paper strip will be fed forward and the advance endwill enter the throat 55 .and pass between the presser-member GLi andthe upper edge of the felt block G3. It will be noted that the plate 54has a forwardly and downwardly inclined portion 54d 4-which leaves anentrance angle above the rear upper corner of the 'felt pad. The advanceend of the paper strip enters this angle and is de- .flected and thuscaused to pass beneath the Weighted from end of the presser-member G4.

The hand-lever B which serves to actuate the feed mechanism is adaptedto be thrown rearwardly by the spring 12, as will be readily understoodfrom Figs. l and 9. The sector 5 is provided with a slot 8fL struck on aradius from the shaft B.V The stop 7 is adjustable in said slot. Thestop comprises a bolt 7a which extends through the slot from the innerside of the segment and is equipped with a sleeve 7b against which thehand-lever B strikes at the end of its rearward stroke. The sleeve issecured in position and the bolt clamped to the segment by means of awingnut 7c. The stop 7 can be adjusted to any desired position to enablea strip of any desired length to be served. Ttwill be understood thatthe feed-wheelB3 turns forwardly7 in the direction indicated by thearrow in 6 when the handle B is swung forwardly in the directionindicated by the arrow in Fig. l; and the feed-wheel remains idle whilethe handle swings: rearwardly under the action of the spring l2, duringwhich movement the ratchet-wheel B2 is turned clockwise by the shaft B,as viewed in Fig. 6.

The feed-wheel B3 is equipped with a pawl 59 pivotally mounted on thewheel at 592. This pawl is engaged by a spring 60 mounted on thefeed-wheel at the point 602. When the ratchet-wheel B2 is turnedclockwise, as viewed in Fig. 6, the pawl rides freely over theratchet-teeth. When the ratchet-wheel is turned counter-clockwise in thefeeding movement, the feed-wheel is caused to turn counter-clockwise.

ln Fig. 16, the ratchet-wheel is replaced by a toothless wheel BG whoseperiphery is engaged by a spring-pressed friction-pawl 59b whichoperates like a ratchet.

The operation of the machinev may be briefly stated: The roll of strippaper is mounted in the chamber D2. If a narrow strip is employed, theroll is mounted on the shaft 28 and the ends of the shaft are journalledin the slots 31, as shown in Fig. 10. On the other hand, if a wide stripis employed, the shaft is omitted and the roll is simply dropped intothe roll-support D3, and held in upright position by the flanges 26. Thestrip passes over the throat ortion 2c of the cast metal frame-member 2and beneath the guide-member 21 which is springpressed and which carriesthe idle feed-roll C. The strip then passes forwardly over the top-wall2b and beneath the floating presser-member 44. The forward feed of thestrip is effected by means of the handlever B which serves to turn theshaft B against the force o'f the spring l2. In the feeding operation,the strip D is fed forwardly from the position shown in Fig. 6 andpasses between the presser-member G4 and the upper edge of the capillarymoistener-element G2. The gummed surface is effectively wetted duringthe passage. During the forward swing of the hand-lever B',

the knife-actuating spring D5 is flexed, or placed under torsion, andthus tends to depress the lever 'E2 and throw the cutter-lever Edownwardly. This action is resisted by the latching device F until thehand-lever B reaches the end of its forward swing, whereupon thehand-lever strikes the triparm F, thus causing the lever E3 to bereleased. The spring B5 then throws the cutter-arm E downwardly by aquick move-A ment, and the pointed blade 89 thus is caused to pierce andsever the strip. The operator then withdraws the severed strip from themachine.

The machine described is thoroughly practicable and is reliable in itsaction. The strip-severing device E operates quickly and reliably byspring action, and the blade 39 works with a piercing action through theslot of the die-plate 34. The font G and attendant parts mounted thereonmay be removed as a unit by lifting the front portion of the fontslightly and then withdrawing the font through the open front end of thecasing. This enables the font to be readily cleansed and the felt pad G3to be cleansed and adjusted with facility. The water supply in the fontcan be replenished, however, without re- Bof moving the font from themachine, the spout 49 proj ecting` sufficiently in front of the holderG2 to enable water to be poured into the font.

The invention provides for due economy in the manufacture and assemblyof the parts; provides against rust by the employment of non-rustingmaterials where exposed to moisture; and provides against leaving in themachine any wetted portion of the strip. The danger of the partsbecoming gummed, or fouled, is reduced to a minimum.

The foregoing detailed description has been given for clearness ofunderstanding only, and no unnecessary limitations should be understoodtherefrom, but the appended claims should be construed as broadly aspermissible, in view of the prior art.
